Polyoxymethylene (POM) Resin: The High-Performance Cornerstone Reinventing Industrial Manufacturing

Performance Analysis: Outstanding Properties Enable Diverse Advantages

Exceptional Mechanical Strength
Tensile Strength: 60–70 MPa, comparable to some metal materials, ensuring resistance to deformation under high stress.
Bending Modulus: 2.5–3.0 GPa, providing robust structural support for load-bearing components.
Wear Resistance: Low friction coefficient (0.1–0.3 under dry friction) makes it ideal for sliding/rotating parts like gears, pulleys, and sprockets, reducing wear and extending equipment lifespan.
Fatigue Resistance: Withstands millions of cyclic stress cycles without failure, suitable for components subjected to frequent start-stop or periodic loading.

Excellent Chemical Stability
POM resists organic solvents, oils, weak acids, and alkalis, maintaining integrity in complex chemical environments. For example, in automotive engine compartments, POM parts (e.g., fuel pump gears) endure motor oil, coolant, and high temperatures without swelling or corrosion. However, it may degrade under extreme conditions of strong acids, alkalis, or high-temperature humidity.

Reliable Thermal Performance
Heat Deflection Temperature: 136–162°C (under 0.45 MPa load), with a continuous use temperature of 85–105°C, suitable for applications requiring moderate heat resistance.
Low Thermal Conductivity: 0.22–0.35 W/(m·K), offering insulation properties for thermal management in electronic devices.

Superior Electrical Insulation
Volume Resistivity: 10¹³–10¹⁴ Ω·cm, with a dielectric constant of 3.7–3.9 (at 1 MHz), maintaining stable insulation performance across wide temperature/humidity ranges and frequency bands.
Applications: Ideal for electrical components like switches, terminal blocks, and electronic housings, minimizing risks of leakage or short circuits.

Versatile Processability
POM’s excellent melt fluidity enables precise fabrication via injection molding, extrusion, blow molding, etc., with short cycle times and high efficiency. This makes it suitable for mass-producing complex-shaped parts, meeting rapid industrial demand.
